' 3'Cla'ims. (01. 121-160) This invention relates to amotor and it aimsto provide a novel construction which is driven by water power.

One object is to provide such an apparatus having hydraulic cylindermechanisms adapted to apply power impulses one hundred and eightydegrees apart to a driven shaft.

It is also aimed to provide in such a motor, a novel water admissionvalve structure and control therefor; a construction wherein there issufficient clearance to enable the fluid pressure to leave the cylinderwas not to interfere with the operation of the piston therein, and toprovide means adapted to be held coupled sufficiently long toenablepressure to build up and the means to function as a governor.

The more specific objects and parent from a consideration of thedescription following taken in connection with accompanying drawingsillustrating an operative. embodi ment.

Referring specifically to the drawings wherein like reference charactersdesignate like or similar parts, the operating parts of the motor aresuitably supported and preferably upon a rigid skeleton framework It)having a base A'driven shaft I2 is journaled in suitable. bearings |3 onsaid framework and is held against longitudinal plane displacement bymeans of collars l4 or any equivalent thereof. Framework I0 has similarshelves or supports l rigid therewith on'opposite sides thereof and eachshelf supports a hydraulic cylinder and piston mechanism generallydesignated l6, adapted to drive or rotate the shaft |2. Power from theshaft |2 may be taken off or transmitted in any suitable manner and forinstance by a belt (not shown) trained over a pulley l1 keyed to saidshaft I2.

advantages will in part be pointed out and otherwise become ap The wateror other motive fluid is supplied underthe desired pressure through apipe or conduit l8 controlled by a valve l9. Pipe l8 leads to a fitting20 which may be secured to the framework l0 and from the fitting branchpipes or conduits 2| lead to a control head 22 rigidly mounted upon therespective shelves l5.

Each control head 22 is preferably made of a plurality of blocks 23 and24 secured together as by means of bolts 25. Each hydraulic device |6consists of a cylinder 25 screwed or otherwise fastened as at 21 to theblock 24. A piston 28 reciprocates within each cylinder l6 and has a rod29 extended exteriorly thereof. The block 24 has a passageway 3|]therein communicating with the cylinder 26 and communicating withpassages 3| and 32 in the block 23 and a passage 33 provided through astuffing box nipple 34 screwed or otherwise fastened as at 35 in thblock 23.

Another nipple 36 is screw threaded as at 31 to the block 23 and has abore communicating with passage 32 and the bore of the adjacent branchpipe 2|, the latter having a flange 38,- overlapped by a cap nut 39screw threaded at 49 to the'nipple 35. g A ball valve 4| is located inthe passage 32 and urged into engagement with a seat 42 on the nipple34, by an expansive coil spring 4-3 positioned by the nipple 36. Saidvalve 4| is disengaged from its seat 42 and so held at the proper time,through the sliding of a rod 44 against the same.

Exhaust water from the cylinder l5 passes therefrom through a chamber orpassage 45 in the block 24, incommunication with passage 39 thereof. Anipple 45 is screw threaded as at 41 into passage 45 and its inner endconstitutes a valve seat at 48 engagea'ble by a ball valve 43. Thelatter valve is adapted to be displaced through the raising of a rod 59.

The reciprocating motion of the piston rod 29 is imparted to a crosshead5| to which the piston rod is fastened. Such crossheads are slidablymounted on guide rods 53, mounted in lugs 54 rising from brackets 55secured to the shelves l5. Pivotally' connected to the crossheads 5| asat 55, are pitmen 51, in turn pivoted at 58 to crank 'arms 59 rigidlysecured to opposite ends of the driven shaft l2. It is to be noted thatthe cranks 59'are fastened to the shaft one hundred and eighty degreesapart so that one hydraulic cylinder device l6 will drive the shaft I2while the other is exhausting.

A bracket 60 is fastened to one side of 'each block 23 and has spacedparallel wings 6| and 52, in which the rod 44 is slidablecolla'r'orthe-like" 63, is'adjustably. screwed or otherwise fastened as at 640mrod 44, between the wings 5 'and 62 and an expansive coil spring Anabutment and is located below the wing 62 and adapted to:

engage the same to limit the upward movement of rod M, as shown inFigure 3; A vertically slidable rod 69 has a bearing in: a'verticaiopening 10 in block 24 and it is secured as by means of a screw H to thehead 6'61 Belowthenipple 46, rod 69 carries a block 12 and block1-2carries the previously mentioned rod 50. Block 72 may be rigidly andadjustably' secured to the rods 69 and 58, by means of screws 13- and'14, respectively.

Other brackets 15 rise from the block 23- and long levers 15 are pivotedtheretolon horizontal axes at IT and such-levers extend across the ad'-'jacent heads 6% so as toengage and depress them" at times. At the endsremote to the pivots l1, levers (6 are guided in slots 18 of verticalguide members 19 rising from the respective wings I53 Depending fromeach lever i6 adjacent the guide members 79, is an arm 80 havingalateral lug 8| at the free end arranged for depression through contactwith a crank 82 rigid on the driven shaft H, such cranks specificallyhaving lateral lugs or rollers 83 which directly engage the lugs 81-.

Said levers 1'6 at a point intermediate the pivots l1 and arms 80, havedependents 84 having lateral lugs 85' which are engageable againstbeveled surfaces 85 of latch levers 8! in order-to displace such latchlevers and then snap under hooks 88 thereof. Such latch levers 8 1 arepivoted as at 89'to suitable mountings 9i)" rigidly bolted as at 9| tothe adjacent wing l5, and

which mountings include contractile springs; 92',

connected thereto and to the levers 8T, urging such levers into thelug-engaging position of Figure 9. Such latch levers 8 1 also includetrip arms 93, the latter-being disposed in thepath of upward movement ofthe lugs 83, as shown in 1 Figure 9, so that the latches may be'tri'ppedor rocked to disengage lugs 85 and enable the levers 76 to swingupwardly on their pivots 'I'l, because heads 66 are in contact with suchlevers'and the rods 44 and heads 66 are subject to the expansive actionof the springs 65.

In the operation of the motor, with the parts in the position of Figure3', and water being supplied through the pipes, 18' and 2|, the valve 4!will be lowered through the depression of rod 44, and the water underpressure will enter the adjacent cylinder 26 because the lever 1-6 willbe lowered through the contact of lug 82 with the lug 8 I, therebydepressing thehead 6'6 with which the rod 44 is rigid, the valve 59'being seated during this operation. Continued downward movement of lever16 causes lug 85 to displace the latch 81 and then snap into engagementtherewith. Such latch through said engagement holds the valve 4! open,long enough to enable pressure to build up in thecylinder IS. Theholding of such valve ll open is for a short period of: time since thecontinued rotationof driven shaft 62 moves lug 83 into engagement withthe trip arm 93 of latch lever 81, thereby rocking such lever againstthe tension of spring 92. and releasing the lug 85, so thatthe leverreturns to normal or uppermost position. under urgency of the spring 65.At the proper sequence of operation,

the rod 50 is raised, contacting ball 49, displacing it from its seat sothat the water may escape or exhaust from the adjacent cylinder throughthe nipple 46.

Itwill" be: realized that the hydraulicdevices on opposite sides of theapparatus, operate in timed sequence one hundred and eighty degreesapart soithat the maximum power derived will be applied. to the drivenshaft I2.

Various changes may be resorted to provided they fall within the spiritand scope of the invention.
